Adding ‘drop shadows’ to your HTML INPUT fields with CSS

Eventually there comes a time when either you, or your client(s) want you to make your HTML <form>’s sexier… one of the simplest approaches you can take is the addition of a ‘drop-shadow’ to the ‘text’ entry box. One new image and some simple CSS and you’re done!

For the purposes of this article, lets use the image i have here ().

Now for the CSS….
If you’re doing this inline it’ll cause you less trouble if you have a large site and only want this in a few locations.<input type="text" style="background:#fff url(/images/input_white.png);" value="" />

NOTE: There are better ways to do the above, but i showed the above to make the implementation obvious.

Now, we can stick the above in an external CSS and use some more specificity to prevent other problems that we’ll elaborate on…PROBLEM…
If you assign the CSS to the <input> tag itself, you’ll get the undesired background on your CHECKBOX, RADIO, and SUBMIT input types.
The fix… either use a ‘class’ for the cases where you want to apply this style… alternately, apply a ‘class’ for the cases that you don’t want this style.
Future (not well supported currently)… use the ‘type’ in you CSS definition, like so..input[type='text'] { background:#fff url(/images/input_white.png); }NOTE: there’s a method in MSIE to use the ‘expression’ concept in your CSS, but i advocate ‘standards’ here, so we won’t delve any further into that topic other than to say it ‘exists’!

So here’s our final approach/recommendation for ‘current’ browsers (in our designs)… you’ll get the shadow ONLY on ‘text’ and ‘password’ input fields and not on the others…

WARNING: the background image we use in the example above is only 200px wide, if your text field is larger than that you’ll need to account for it in some way! (otherwise you’ll get a tiled background or run out of ‘shadow’)

More advice…

You can also apply this technique to <textarea> using a similar approach!

This may also be a useful way to indicate ‘errors’, ‘required fields’ or ‘passwords’ in a Rich UI.
